Application led December 15, 1925. Serial No. 75,649.

This invention relates to improvements in flour sitters and the like and has tor its object to provide a combined container and sitter, and means tor closing the bottom thereof.

Another object o t the invention is to provide a flour sitter having means whereby it may be held and actuated by one hand ot the user.

A further object ot the invention is to provide a ilour sitter having a bottom intermediate ot its ends and a sitter suspended under said bottom, and manually controlled means tor sitting the flour without the necessity ot shaking the sitter.

With the above and such other objects as may hereinafter more tully appear, I have invented the -device illustrated in the accompanying drawings, in which:

Figure 1 is an elevational view of my improved Sitter.

Figure 2is a top plan yview thereof.

Figure 3 is a vertical sectional view ot the device.

Figure 4 is a view similar to Figure 2, certain parts being in changed osition.

Like reference characters indicate like parts throughout the following specification and in the several views in the drawings, in which 1 indicates a sitter consisting ot a cylinder 2 havin a handle 3, to the upper end ot which is pivotally connected a fingeractuated member 4 .held normally in extended position b means ot a spring 5. Projecting throug a horizontal slot 6 in the lower portion ot the cylinder 2 is a lever 7 having an opening through which' the rod 8 carried b the member 4 movably projects, whereby the lever 7 will be reciprocated through the movement of the member 4. Suspended within the cylinder 2 by means ot a horizontal bead v9 is a dish-sha ed sieve 10 having a conical ybottom 11. ounted upon the upper edge 12 ot the member 10 is a bottom 13 provided with a series of spaced apart flaring openings 14. Rotatably 'seated upon the bottom 13 and actuated by means of the lever 7 is a shutter 15 having a series ot spaced-apart shutter members 16 of a shape to close the openings 14 in one position of the member 15. Projecting upwardly from one edge of the sections'l are agitators 17, and projecting downwardly trom the other edge ot said sections are similar members 18, the side and bottom edges 19 and 20 ot which are ot a contour to fit snugly the bottom and side walls ot the sieve 10, whereby, upon the rot-ation ot the member 15, the flour on the sieve will be torced therethrough. The agitators 17 operate directly under the flour in the cup or cylinder, thus keeping the Hour trom packing and causing a certain amount thereof to pass through the openings 14 during the reciprocation ot the memberA 15.

From the above description, it will be seen that I have provided a sitter tor flour or other material which may be held by its handle in the hand ot an operator whose fingers may be contracted and relaxed, which action, with the co-action ot the spring 5, will cause the backward and torward movement ot the lever actuated member 4, whereby the shutter 15 will be rotated in a reciprocal manner, causing the flour to be agitated and sitted.

Having described my invention, that which I claim as new and desire to procure by Letters Patent is:

1. In a sitter having a horizontal wall with openings therein, a sieve mounted under said wall, and means tor causing the contents ot the sitter to pass through said openings into said sieve and agitating the lour upon said sieve, said ,means consisting ot a rotatable shutter on said wall.

2. In a sitter having a horizontalwall 4with openings therein, a sieve mounted under said wall, and means for causing the contents ot the sitter to pass throu h said openings into said sieve and agitating, theflour upon said sieve, said means consisting ot a rotatable shutter on said wall, and means tor causing the rotation ot said shutter. y

3. In a sitter having a horizontal wall with openings therein, a sieve mounted under said Wall, means tor causing the contents ot the sitter to pass through said openings into said sieve and agitatng the flour upon said sieve, said means consisting ot a rotatable shutter on said wall, and means tor causing the rotation of said shutter, said means being manually controlled.

4. In a sitter having a horizontal wall with openings therein, a sieve mounted under said wall, means tor causing the contents ot the sitter to pass through said openings into said sieve and agitating the tlour upon said sieve, said means consisting ot a rotatable shutter on said wall, and means tor causing the rotation of said shut llt) ter, said'means being manually controlled and consisting ot a pivotally mounted shutter-actuated member.

5. In a sitter having a horizontal 'wall with openings therein, a sieve mount-ed under said wall, means tor causing the oontents ot the sitter to pass through said openings into said sieve and agitating the flour upon said sieve, said means consisting ot a rotatable shutter von said wall, means tor causing the rotation ot said shutter, said means being manually controlled and consisting ot a pivotally mounted shutteraetuated member, and a spring tor maintaining said member in a normal position.

6. In a sitter having a horizontal wall with openings therein, a sieve mounted under said wall, means tor Causing the oontents ot the sitter to pass through the opens ings into said sieve and agitating the flour upon said sieve, said means consisting ot a rotatable shutter on said wall` means tor causing the rotation ot said shutter, said means being manually controlled and consisting ot a pivotally mounted shutter-actuated member and a spring tor maintaining said member in a normal position, said meniber having a lever projecting through a slot in the wall ot said sitter and engageable by said pivoted member.

7. A sitter comprising a body having a bottom with openings therein, a shutter controlling the openings, a screen below the shutter, blades on the shutter engaging the screen and means tor operating the shutter.

8. A sitter comprising a body having a bottom with openings therein, a shutter oontrolling the openings, a screen below the shutter, blades on the shutter engaging the screen, a handle connected with the body, an arm pivoted to the handle and adapted to be actuated by the fingers ot the hand grasping the handle and means tor connecting the arm to the shutter.

9. A sitter comprising a body having a bottom with openings therein, a shutter controlling the openings, a screen below the shutter, blades on the shutter engaging the screen, upwardly extending blades on the shutter passing through the openings in the bottom, a handle on the body, an arm pivoted to the handle, and means tor Connecting the lower end ot the arm with the shutter.

10. Vlin a sitter a sieve and means tor supporting the bulk ot material being sitted trom the sieve, said means including a shutter, agitators carried by the shutter.

11. n a sitter a sieve and means tor supporting the bulk ot material beingsitted trom the sieve, said means including a shutter, agitators carried by the shutter, a wall above the sieve.

l2. In a sitter a sieve and means tor supporting the bulk ot material being sitted trom the sieve, said means including a shutter, agitators carried by the shutter, a wall above the sieve, said agitators operating above and below the wall.

In testimony whereof l affix my signature.
